DUMPlNG-CAR.

V SPECIFICATION forming part of Letters Patent No. 244,795, dated July26, 1881.

Application filed April 26, 1881. (No model.)

To all whom it may concern:

Beit known that I, JOHN T. GROWTHER, of Oarbondale, in the county ofJackson and State of Illinois, have invented a new and usefulImprovement in Dumping-Oars, of which the following is a specification.

My invention relates to a car which is more particularly intended to runupon rails, and it may be used in building railways, or for carrying oreor coal at mines, or for loading or unloading grain, and for variousother purposes.

The invention consists in combining racks and pinions with the sectionsof a dumpingcar, as hereinafter described.

In the accompanying drawings, Figure l is a top view of a carconstructed according to my invention when made in one form. Fig. 2 is aside view of the same. Fig. 3 is a side view of another form of theinvention, and Fig. 4 a detail view of a portion of the same.

The car is supported by a frame-work consisting of side rails, A, endpieces, B, and diagonal side braces, G, which frame-work rests upontrucks D, like an ordinary car.

The car is made in two sections, E E, with their inner ends open andadjacent to each other. side rails, A, by a shaft, 6, so as tooscillatein a vertical plane. The shaft 0 is located at a point beyondthe longitudinal center of the section, so that the portion of thesection between the pivot and the inner end is heavier than the portionbetween the pivot and the outer end.

To the inner end of each section, when made in the form shown in Fig. 1,is attached the 1ower end of a chain, G, the upper end of which isattached to a Windlass, H, journaled in two Each section is pivotedbetween the posts at'the sides of the car, midway of its length. TheWindlass is provided with a ratchet, h, and pawls i.

To the outer ends of the sections are attached chains J, having theirinner ends attached to the Windlass.

When the sections are raised to a level with each other they are held inplace by buttons L on the under side of the frame, together with thechains and the Windlass and its ratchet and pawls.

When the load is to be deposited, the buttons are turned free of thesections, and the pawls are raised free of the ratchet, so as to allowthe windlass to turn, whereupon the weight of the inner ends of thesections cause them to drop to the positions shown in dotted lines, soas to deposit the load beneath the center of the car, after which thesections are raised to the proper level by means of the Windlass andchains, and secured by the buttons, as above described.

When th car is madein the form shown in Figs. 3 and 4, instead of thewindlass and chains, I'employ racks M on the inner ends of the sectionsengaging with pinions P, worked by a hand-wheel, Q, on a shaft journaledin the frame-work.

Having thus fully described my invention, Iclaim as new and desire tosecure by Letters Patent- The combination, with the sections E E, of theracks M and pinions P, substantially as and for the purpose hereindescribed.

JOHN T. GROWTHER.
